Steve is the VP of the MC. He's autistic, talks funny—especially when stressed, and swears like a sailor. His mind works like a machine, focusing singularly on potential problems and clearing them with precision and stealth. 
Military trained as a SEAL, he was a satellite for his team, but rarely involved with them. Working alone is what he’s best at, doing it quietly is what he excels at, and eliminating a threat to his MC family is what he was born to do. 
When he turns that focus on Jess she doesn't stand a chance and her natural sub tendencies are a perfect fit. 
Jess is content being single, but after three years of being asked out she finally says yes to Steve. Jess lives with a debilitating ailment and is determined to hide that from her new MC family. Using her finance degree, Jess helps the MC stay out of the drug trade and they offer protection from union bosses in return. Pres and Jess work together to make the businesses profitable enough to keep his MC going and growing. 
Keeping drugs out of their newly attained, clean world is a challenge that Steve will not walk away from, especially when Jess becomes a target.
